Bob O’Neill, president of the Grant Park Conservancy, said that if he didn’t know better, he might be tempted to say that himself.

“Normally, I’d walk up here and I’d see this and I’d be really upset,” he said.

But O’Neill said that with some of the profits from Lollapalooza plugged back into Chicago parks and programs, it’s well worth the trouble.

“This helps keep taxes dollars down because the Park District doesn’t have to raise tax dollars if they can raise the money privately. It supports parks throughout the city, so bear with us, this will be restored,” O’Neill said.

Besides bringing visitors from around the world and tens of millions of dollars into the local economy, O’Neill said it contributes about $2 million for environmental programs, on top of the money that concert organizers will pay to repair damage to the park.
